Target of the paper
The Role of Open Standard and Interoperability For Smarter Distribution Management System
Overview of the electricity network in Al Ain Area…1
•Area of about 13,000 km2.
•Total no. of consumers > 106,000 and maximum load ( 2010) of 1799 MW and energy consumption of 7950.88GWh
•Expected load by 2014 is 2869 MW (55% up) with energy consumption of 13520.236 GWh and expected number of over than 170,000 consumers
Overview of the electricity network in Al Ain Area…2
• From the transmission (400/220kV) to the distribution (33/11/0.415) kV
• Type of substations:– Primary substations 33/11kV– Secondary distribution substations 11/0.415kV
Overview of the electricity network in Al Ain Area…3
•Type of substations:1. Primary distribution
• Firm capacity 30 to 60 MVA• No. of switchgears: 10 of 33 kV & 24 of 11kV or
3 of 33 kV & 5 of 11kVBrick Built Package Unit1980’s & 1990’s >2000
Overview of the electricity network in Al Ain Area…4
•Type of substations:1. Secondary distribution
• Firm capacity 1MVA to 3 MVA• No. of switchgears: 2+1 (RMU) to 2+2 (Brick Built)
Old Distribution Substation Case Study
Substation Control Points before IT integration – Local Control Point – Substation Control Point

Adaptation of IT in Existing Substations
& Integration to DMS • Remote terminal unit (RTU), a
MP based system built in a modular system – The RTU monitors and controls the substation – Periodic measurement, acquisition of events, stamping all
events by 1 ms resolution time, and communicate to IED’s
• Data exchange through wireless media (GSM/GPRS) or pilot cables along with power cables (33kV)

Communication to DMS, GPRS & Copper Wires
New substation case study
• SCMS system was adapted• Easy to upgrade; software and hardware
New substation case study.. Smart Grid ready !
• Design of new substation were revised and equipped with the latest IT equipment to formulate SCMS along with the integration to the DMS

Future plans… Short term
• Establishing AADC communication Network– Fiber optic network • Power cables• Sewage pipelines
– Meshed Wireless Network
Future plans… Short term
• 11 kV Ring Main Unit Substations' Automation • 11 kV Overhead lines Auto-Reclosers and
sectionalizers' Automation
Wireless Communication
Future Plan… Long term
• Connection of outage management system to the DMS.
• Integration of AMR system to DMS• intelligent houses, possible green energy sources
and even recharging electric vehicle
Conclusion
• No system can be built on only open standards without introducing customized solutions
• Customized solutions must fulfill sufficient level of interoperability
• A regulator must participate in standards revision and to set the rules for interoperability
